[mythtv-users] [Solved] Waiting for database upgrade schema lock error

Hi Folks!

Answering myself to give a couple of potential solutions to someone else 
stumbling on this thread.

First, someone else had a similar problem – see “Mythfrontend database 
schema upgrade lock” at 

I intended to give that a try that but wanted to have a couple of 
backups available; had several ‘But First’ issues slow my progress down. 
One of them may have fixed the problem. Late this morning one of my 
Ethernet Switches failed; nothing but a blue ‘on’ light. Swapped out to 
get myself back on-line.

This evening intended to try the referenced thread; checked to be sure 
still having problems but the Frontend went to MythTV menu properly and 
is working fine! Tested and the other Frontend that was erroring now 
works again! Yea!!!

So I had not rebooted the Backend; the two Frontends had been rebooted 
previously but didn’t fix anything. So far me seems like the failure of 
the Ethernet Switch and subsequent disconnect and reconnect of the 
network wiring fixed the problem.
